GAS OR INTERNAL-COMBUSTI-ON ENGINE GOVRNOR.

SPIEGIFIGATIQN forming part of Letters Patent No. 757,311, dated April12, 1904:.`

Application filed September 8, 1903. Serial No. 172,205. (No model.)

To a/ZZ whom it may concern:

Be it known that I, PETER JENNEss, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new `and useful Improvement in Gras orInternal-Combustion Engine Governors, of which the'following is aspecification.

My invention consists of a novel construction of a gas orinternal-combustion engine governor, which is especially adapted to beused in connection With engines employed in automobiles; and it consistsin the novel construction of mechanism whereby the supply of air and gasto the engine-cylinders is auto'- matically regulated with greateXactness, pro-l vision being also made for readily adjusting theapparatus by the operator according to requirements. r

To the above ends my invention consists of the novel featuresofconstruction hereinafter described, and pointed out in the claims.

Figure 1 represents a plan or diagrammatic View of a gas orinternal-'combustion engine governor embodying my invention. Fig. 2represents a plan View, partly in section, of a portion Vof theapparatus seen in Fig. 1, show? ing the valve in partly-open position.

' Similar numerals of reference indicate cor-` responding parts in thefigures.

Referring to the drawings, 1 designates a cam-shaft, which is mounted insuitable bearings and provided with the gear 2, which is adapted to meshwith the`pinion 3, which is mounted on the engine or crank shaft 4,which is operated by the gas or internal-combustion engine or engines 5,it being of course understood that the engine or crank shaft 4 runstwice as fast as the cam-shaft 1, which operates the engine-valves inthe usual manner.

6 designates lugs on the gear 2, upon which are pivotally mounted thebell-cranks 7, each of which have the pins 8, which engage the groove9'on opposite sides of the sleeve 12, which is splined to the shaft 1,said bellcranks or elbow-levers 7 being provided with the balls 10,which are held in their proper relative position by means of the spring11.

A13 designates a spiral contact-on the sleeve 12V for advancing thespark, said sleeve being also provided with agroove to t the ring 14,

which is pivotally connected to the bell-crank 15, which is fulcrumed atthe point 16.

17 designates a rod leading from an arm of the bell-crank'l to the arm18 of the bellcrank 19, which has the arm 20, to which one end of thelink 21 is connected, the opposite end of said link being connected tothe arm I22, which operates the throttle 23, which controls thedischarge of the gas from the commingling-chamber 24 through the outlet25 to the engine-cylinders. pivoted `at the point 26 to the arm orlever27, which isfulcrumed at the point ,'28, said arm 27 havingconnected thereto the rod 29, which is operated by any suitable means.A

30 designates the float or gaSOlene-chamber ofthe carbureter 31; but asthese parts form no part of the present invention per ,se I have deemedit unnecessary to describe the same in detail. i n

32 designates the'contact-strip employed, the function of which will beevident.

' I have also deemed it unnecessary to show or describe .the wires orother connections whereby the ignition is effected, since the construction of the same will be familiar to those skilled in this art;

The bell-crank 19 isl The operation is as follows: As will beap'- parentto those skilled in this art, the governor comprises the elbowlevers 7and the ballsv 10 and operates the sleeve 12,. having the spiral contact13v thereon for advancing the' spark, and by means of the ring 14 andits adjuncts the bell-crank l5 is operated to the desired extent, saidbell-crank being connected to the throttle or air valve 23 by means ofthe link or connecting-rod 17, the bell-crank 19, and the rod or link21, as has already been eX- plained. It will be apparent that thethrottie-gate or air-valve 23 closes or tends to close as the spark isadvanced by the governor, according to the position of the arm or lever27, on which bell-crank 19 is pivoted, said lever 27 being itselfpivoted at the point 28, as has been explained, it being furtherapparent that the position of the pivot of the bell-crank 19 is readilycontrolled by means of the rod .29, which leads to any desired point andmay It will be apparent from the foregoing that by my invention thenumber of parts is reduced to a minimum and the construction greatlysimplified, so that but a single throttle is necessary for bothgoverning the charge admitted to the cylinders and for admitting more orless gas by independent means at the will of the operator.` It willfurther be apparent that the spark is automatically retarded wheneverthe motor is stopped, it being immaterial at what position theindependent controlling device may be set.

It will be apparent that changes may be made by those skilled in the artin the manner of assembling and constructing the above parts, and I donot, therefore, desire to be limited in every instance to the exactconstruction I have herein shown and described.

. Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a device of the character named, a carbureter, a throttle-valve, agovernor, connections between said governor and throttle, a bell-cranklever which forms a part of. said connections, a pivoted arm carryingthe fulcrum of the bell-crank lever, and hand-controlled means formoving said arm and thereby the throttle, whereby but a singlethrottlevalve is employed for vboth governing the charge admitted to theengine-cylinder and for admitting more or less gas independently at theWill of the operator.

2. In a device of the character named, a cam-shaft, a sleeve splinedthereupon for longitudinal movement, a spiral contact on said sleeve, a.governor adapted to actuate said sleeve, a carbureter, athrottle-valve, connections between said governor and throttle,l abell-crank lever which forms a part of said connections, a pivoted armcarrying the fulcrum of the bell-crank lever, and hand-controlled meansfor moving said arm and thereby the throttle, whereby but a singlethrottlevalve is employed for both governing the charge admitted to theengine-cylinder and for admitting more or less gas independently at thewill of the operator.

3. In a device of the character named, a governor, a carbureter, asleeve, connections between said governor and sleeve for moving thelatter, a bell-crank actuated by the movement of said sleeve, a secondbell-crank, a rod connecting said bell-cranks, a lever or arm pivoted toa fixed point, said last-mentioned bell-crank being pivoted to saidlever, means for adjusting the position of said lever, a throttle-valvefor said carbureter and connections intermediate said last-mentionedbellcrank and said throttle-valve.

4. In a device of the character named, a longitudinally-movable sleeve,a spiral contact thereon, a cooperating contact, a groove in saidVsleeve, a' governor adapted to move said sleeve longitudinally, a ringin engagement with said groove, a bell-crank pivoted to a iiXed pointand connected Vto said ring, a second bell-crank, a rod common to saidbellcranks, an arm or lever upon which said second bell-crank ispivotally mounted, said arm being pivoted to a xed point, a carbureter,a throttle-valve for said carbureter, connections intermediate saidsecond bell-crank and valve, and means for adjusting the position ofsaid second bell-crank.

5. In device of the character named, a governor, alongitudinally-movable sleeve having a groove therein, connections fromsaid governor engaging said groove, a spiral contact 13 on said sleeve,a cooperating contact, a ring 14 engaging a second groove in saidsleeve, a bell-crank 15 connected to said ring, said bell-crank beingfulcrumed at a xed point, a second bell-crank 19, a rod 17 connectingsaid bell-cranks, a lever 27 fulcrumed at a Xed point 28, saidbell-crank 19 being pivoted to said lever, a carbureter having acommingling-chamber 24 therein, ar valve 23 controlling the discharge ofgas from said commingling-chamber, an arm 22 for actuating said valve, arod 21 intermediate said arm and the bell-crank lever 19, and a rod 29for adjusting simultaneously the position of said lever 27 and saidbell-crank 19.
